Pump Features & Benefits

Use the chart below to see what feature is available for each product

S-Tube Impeller:
Substantially reduces risk of clogging through an uncompromised, free-passage design and uniform inner diameter. With no leading edges, the S-Tube significantly reduces clogs when compared to a traditional impeller as there is nothing waste matter can catch on.

Super Vortex Impeller:
Offered as an alternative on our SE and SL pumps, the Super Vortex impeller has a patented design for very fibrous materials. The design allows the material to pass freely through the pump without getting caught by keeping the flow outside the impeller and creating a vortex to move material through.

Channel Impeller:
Customizable for operation requirements, channel impellers have long vanes that help reduce the risk of jams and clogs.

MKII Hydraulic End:
Allows for improved fiber handling ability with improved wear resistance of the sealing system. The patented threaded sealing system passes the fibers, grease and sand completely out of the sealing gap to ensure durability against the wear.

Smart Trim System:
Restore factory-set impeller clearances easily yourself to keep impellers at optimum efficiency.

The SE 12-42 hp range of submersible wastewater pumps from Grundfos feature the following three hydraulic concepts:

  • Grundfos Open S-tube® semi-open impeller hydraulics (offered for SE/SL pumps fitted with Superhigh -or High head hydraulics. Open S-tube® semi-open impellers provide high efficiency over a wide operating range. They can be trimmed to meet a specific duty point, and SE pumps fitted with Open S-tube® impellers are the ideal solution for medium to extreme contamination of wastewater.
  • Grundfos closed S-tube® hydraulics (offered for SE1/SE2/SL1/SL2 pumps fitted with Superhigh -, High -, Medium -, Low and Extra low head hydraulics) or S-tube® closed impellers provide large free passage and high efficiency. SE pumps fitted with the closed S-tube® impeller are ideal for low to medium contaminated wastewater.
  • SuperVortex free-flow hydraulics (offered for SEV/SLV pumps). SuperVortex free-flow impellers are ideal for challenging applications with high abrasives content or long fibrous materials.

When combined with intelligent controls and high-efficiency IEC and IE3 motor components, the SE 12-42 hp range of pumps provide an ideal solution for challenging wastewater applications.
